Don't forget to pencil Museum Day on your Sept. 30th calendar! In cooperation with the Smithsonian, select museums will offer free, one-time admission to the public. Here's a link for more information. In Tennessee's list, the best choice seems to be Andrew Jackson's home, the Hermitage. It's pricey for a regular visit. They do offer free admission on Andrew Jackson's birthday, but I understand it's quite crowded then. I have a feeling Museum Day will be a little less publicized.
